Read the first 7 Monitoring, Feedback & Security flashcards as text

  1. Which Azure Monitor feature lets you group related alerts into a single notification to reduce alert fatigue during an incident?

    Answer: Smart alert grouping (alert correlation)

    Smart alert grouping in Azure Monitor correlates fired alerts that are likely related into a single incident, reducing notification noise.

  2. Your pipeline must enforce that only signed container images are deployed to AKS. Which Kubernetes admission mechanism combined with Azure Policy achieves this?

    Answer: Azure Policy for AKS using the image signature verification constraint

    Azure Policy for AKS supports image integrity policies that verify image signatures (via Notation/Ratify) before allowing pods to start.

  3. A developer wants to see real-time telemetry while debugging a locally running service instrumented with Application Insights. Which feature streams live data?

    Answer: Live Metrics Stream

    Live Metrics Stream in Application Insights provides near-real-time telemetry (within 1 second) from a running application for immediate feedback.

  4. You need to ensure that Azure DevOps pipeline artifacts are not tampered with between stages. Which practice best addresses this supply chain security concern?

    Answer: Sign artifacts with a code-signing certificate and verify the signature in downstream stages

    Signing pipeline artifacts and verifying signatures in downstream stages ensures integrity and detects tampering across pipeline stages.

  5. Your SRE team wants to set an error budget based on a 99.9% SLO for an API. Which Application Insights query approach helps track budget burn rate?

    Answer: Write a KQL query calculating the ratio of failed requests to total requests over a rolling window

    A KQL query that computes failed/total request ratio over a rolling window directly measures SLO compliance and error budget consumption.

  6. Which Azure Security Center (Defender for Cloud) feature provides a prioritized list of security hardening actions for your DevOps pipelines and repos?

    Answer: DevOps security posture management (DPSM) recommendations

    DevOps security posture management in Defender for Cloud surfaces actionable recommendations specific to repositories, pipelines, and code security.

  7. You configure an Azure Monitor alert that fires when CPU exceeds 90% for 5 minutes. The alert sends an email but your team misses it. Which improvement reduces missed alerts?

    Answer: Add an Azure Logic App action to the action group to post to Microsoft Teams

    Adding a Logic App action to post to Teams ensures the alert appears in the team's primary collaboration channel, reducing the chance it is missed.
